Implementation of a module for adding pictures using rails Active_Storage gem. Below is the list of steps that are made to implement the module in the repository.
Initialize the rails application.
rails new picture-module -d mysql -T
-T removes the test gem that is preinstalled. I prefer rspec.
get into the application file directory.
cd picture-module
run bundle to install the pending gems.
bundle install
then create the database
rails db:create
do a database migration to get initial values to the databases created
rails db:migrate
start the server to confirm that all worked well. check out localhost:3000 in the browser
rails server
create the model, view and controller for the photo to be added. This implements scaffold which helps to do all that.
rails g scaffold photo title caption:text
migrate the values into the database
rails db:migrate
now restart the server with "ctrl + c"
make a root for you application in config/route.rb. add:
root to: 'photos#index'
check out localhost:3000
Now, add the active storage gem into your application.
rails active_storage:install
run the migration for the active storage data
rails db:migrate
add the variable for holding your photo into app/models/photo.rb
has_one_attached :photo
add the variable into the controller paramitters app/controllers/PhotosController.rb
change "params.require(:photo).permit(:title, :caption)" into:
params.require(:photo).permit(:title, :caption, :photo)
make the photo visible in the views. add the code below to app/views/photos/form.html.erb this will display the photo
<p>
<%= image_tag(@photo.photo) %>
</p>
#you can add some styling to the photo with the code below.
<div>
<%= image_tag(@photo.photo, style: 'width: 200px; height: auto') %>
</div>
make the image clickable
<div>
<%= link_to image_tag(@photo.photo, style: 'width: 200px; height: auto'), photos_path %>
</div>
